So I have 2 crappy video cards.... Looking for some pro advice on how to use them both... They are different cards and my mboard is not SLI... It really is nothing special.. But I am just really curious of what my options are to maybe get the most out of what I have.... For example... could 2nd weaker card work to just be dedicated for PhysX? Or just to be used for a second monitor? Or should I just sell it?

Here are my specs for my budget build I made last January that I am currently am using now.

Ive tested that with 2 monitors on my HD6850 and 3rd monitor on a Geforce FX5200 PCI.
the first card (HD6850) renders all the images and just uses the 2nd card to display output on the third monitor.
Although the PCI bandwidth was too slow so I ended up just using the HD6850 for all monitors.
If your Geforce 6200 is PCI-E, it wont be bandwidth limited and might be fast enough for the 3rd monitor.

SoftTH is a nice program if you have a fast gpu that doesnt support triple monitor gaming like the GTX295 or GTX280
